Initial Update: Wednesday, 7/8/2015 10:49 UTC

We are aware of issues within Application Insights where some telemetry data may have been lost during ingestion in North Europe region. Some customers may have experienced Data Gaps for a brief period of nearly 60 minutes during time window of 07:18 – 08:16 UTC . All the data types are affected by this data loss. In order to mitigate we have redirected ingestion traffic to other regions until North Europe region gets back to healthy state.

Work Around: None
Next Update: Before 7/8 17:00 UTC

We are working hard to resolve this issue and apologize for any inconvenience.
